UNITED MAE WILLIAM R. REED, OF BALTIMORE, MARYLAND.

LADDER.

Application filed June 29, 1920. Serial No. 392,677.

To all whom it may concern.

Be it known that I, WILLIAM R. REED, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Ladders, of which the following is a specification.

This invention relates to improvements in ladders and has for its object to provide a simple, cheap and efficient rest to hold the ladder securely in any desired position and prevent same from slipping.

The invention consists of the novel construction and arrangement of the parts and combination of parts hereinafter more fully set forth in the following specification, and pointed out in'detail in the appended claim.

In the accompanying drawing,

Figure 1 is a side elevation of the lower end of a ladder showing my invention applied thereto.

Figure 2 is a front view of Figure 1.

Figure 3 is a detail side view of the lower end of the ladder showing the lug secured to the side thereof.

Figure 4 is an edge View of Figure 3. Figure 5 is a detail side elevation of the rest.

Referring to the accompanying drawing forming part of this specification and in which like reference numerals designate like parts throughout the several views thereof, 1 represents the U-shaped rests into which the lower ends of the ladder rails 2 project and are held therein by the bolts 3 each of which passes through both sides of the respective rest 1 and through the lower end of the respective ladder rail. The said ladder is adapted to be tilted back and forth on the said bolts 3. Passing through the ends of the ladder rails 2 above the rests 1 is a rod 4: over which the bent portion 5 of the rocking arms 7 are fitted,

Connected to the ends of the rocking arms 7 are links 8 and 9. The links 8 have their lower ends bent at right angles and extend through and across the sides of the rests 1, and the links 9 have their lower ends pivoted in the sides of the-rests 1. i The metal pieces 10 are screw-threaded at one end and are screwed upon the ends of the rod 4 and are held in position thereon by the screws 11 which project into the side rails 2 of the ladder; each of these pieces 10 is provided with an outwardly projectinglug 12 which rests upon the outer surface of the rocking arm 7 the outer ends of the rod 4 are pro vided with pins 13 to hold the rocking arms 7 thereon. Between each of the arms 7 and the pieces 10 is a washer 14.

The ladder may be tilted on the pivot 3 either backward or forward in which position the lug 12 willalways rest upon theupper surface of the rocking arm 7 and through the medium of the links 8 and 9 will hold the rests 1 flat upon the floor oi other surface.

Having thus described my invention what I claim is, i j j The combination with a ladder of U- shaped rests into which the lower ends of the ladder rails project, a bolt passed through each of said rests and through the lower end of the respective ladder rail, a rod extending across the lower end ofv the ladder above said rests, a rocking arm on each end of said rod, links connecting each end of said rocking arm with the respective rest, a lug projecting from each side of the ladder and impinging against the up per surface of the respective rocking arm.

In testimony whereof I affix my signature.

WILLIAM REED.
